Untyped NbE in Typed Racket

An implementation of normalization by evaluation loosely based on A Denotational Account of Untyped Normalization by Evaluation and Abel's thesis on NbE.

Since the implementation is untyped, the normalize function only gives you β-normal forms. However, you can get a little bit of βη-equivalence by invoking Coquand's algorithm (η-eq?) on β-normal forms.
